BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Nemesia plant, botanically known as Nemesia hybrida Vent. and hereinafter referred to by the name ‘INNEMAROPI’.

The new Nemesia plant is a product of a planned breeding program conducted by the Inventor in Gensingen, Germany. The objective of the breeding program is to create new semi-upright and freely branching Nemesia plants with good summer garden performance.

The new Nemesia plant originated from a cross-pollination made by the Inventor in July, 2015 in Gensingen, Germany of a proprietary selection of Nemesia Vent. identified as code number N 15 300-32, not patented, as the female, or seed, parent with a proprietary selection of Nemesia Vent. identified as code number N 07 105-36 tet2, not patented, as the male, or pollen, parent. The new Nemesia plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled environment in Gensingen, Germany in April, 2016.

Asexual reproduction of the new Nemesia plant by terminal vegetative cuttings in a controlled environment in Gensingen, Germany since April, 2016, has shown that the unique features of this new Nemesia plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Nemesia have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘INNEMAROPI’. These characteristics in combination distinguish ‘INNEMAROPI’ as a new and distinct Nemesia plant:

-   -   1. Upright to somewhat outwardly spreading plant habit.     -   2. Moderately vigorous growth habit.     -   3. Freely branching habit.     -   4. Freely flowering habit.     -   5. Long flowering period.     -   6. Light purple-colored flowers that are sterile and fragrant.     -   7. Good summer garden performance.

Plants of the new Nemesia differ primarily from plants of the female parent selection in flower sterility as flowers of plants of the new Nemesia are sterile whereas flowers of plants of the female parent selection are fertile.

Plants of the new Nemesia differ primarily from plants of the male parent selection in flower fragrance as flowers of plants of the new Nemesia are fragrant whereas flowers of plants of the male parent selection are not fragrant.

Plants of the new Nemesia can be compared to plants of Nemesia X hybrida ‘Fleurame’, disclosed in U.S. Plant Pat. No. 17,035. In side-by-side comparisons, plants of the new Nemesia differ primarily from plants of ‘Fleurame’ in the following characteristics:

-   -   1. Plants of the new Nemesia are larger than plants of         ‘Fleurame’.     -   2. Flowers of plants of the new Nemesia are light purple in         color whereas flowers of plants of ‘Fleurame’ are pale pink,         lavender and purple in color.     -   3. Flowers of plants of the new Nemesia are more fragrant than         flowers of plants of ‘Fleurame’.

Plants of the new Nemesia can also be compared to plants of Nemesia X hybrida ‘Fleuripi’, disclosed in U.S. Plant Pat. No. 16,851. In side-by-side comparisons, plants of the new Nemesia differ primarily from plants of ‘Fleuripi’ in the following characteristics:

-   -   1. Plants of the new Nemesia are larger than plants of         ‘Fleuripi’.     -   2. Plants of the new Nemesia have larger flowers than plants of         ‘Fleuripi’.     -   3. Plants of the new Nemesia flower more freely, continuously         and uniformly during the summer than plants of ‘Fleuripi’.     -   4. Flowers of plants of the new Nemesia are more fragrant than         flowers of plants of ‘Fleuripi’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Nemesia plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Nemesia plant.

At the top of the photographic sheet (FIG. 1) is a side perspective view of a typical flowering plant of ‘INNEMAROPI’ grown in a container and at the bottom of the photographic sheet is a close-up view of a typical flowering plant of ‘INNEMAROPI’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the spring in 15.25-cm containers in a polyethylene-covered greenhouse in St. Thomas, Ontario, Canada and under cultural practices typical of commercial Nemesia production. During the production of the plants, day temperatures averaged 27° C. and night temperatures averaged 17° C. Plants were pinched when the rooted cuttings were planted and were eight weeks from planting rooted cuttings when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
